Wrong. Dentists still use the qtip numbing and then bring in that novacaine. Yuck what a disgusting flavor when it gets on your tongue. I like to swish like the nike sign when that happens, friend. The new hotness for new age dentists though are the 360 Xrays. I went to a dentist nervous about them putting those razor blades in my mouth for the X-ray. Friend just had me put my chin on this apparatus and the xray went around my entire head. Done in 30 seconds.
It's not novacaine bruh. i'm not saying that we dont use local anesthesia. we just dont use novacaine. it's extremely outdated. the most used local anesthesia i've seen used as an assistant and in residency is probably Xylocaine.
the stuff on the qtip or what we like to call the cotton tip applicator is a topical anesthesia the reacts to the mucosa known as benzocaine.
